Action figures....but who are they? UPDATED!

A couple of weeks ago I bought a bunch of little action figures from the secondhand market, I thought they might make good 'pretend' BJDs for my bigger dolls as these little plastic figures are multi jointed, although not ball jointed.  I got 5 of them and thought I'd look on the internet to see if they are from a children's cartoon/tv programme/Anime or something.  However, despite quite a bit of research, I cannot find anything similar.  They don't have any markings on them except that each one has a number on the bottom of one foot.

I thought I'd share them on here in the hope that someone might recognise them and might be able to throw some light on who they are and where they come from!  I am hoping that one of my readers, jSarie, in particular, might be able to help!!

So here they are.  They are approx 5 to 6 inches tall, made of all plastic and have moulded on hair, all but the boy with glasses, are multi jointed.  They can stand on their own but not on the artificial grass that I tried posing them on!

This girl looks very Asian with her black hair and almond shaped eyes.  I'm not sure what those brown raised lines are above her eyebrows though!

I think this is a girl because of her pink hair, outfit and pink wings but I could be wrong:

This  yellow haired one, which I think could be a boy, has little 'horns' or at least the 'stubs' of horns on his head, plus a feline sort of tail which is also hinged!  But his feet are more like 'hooves':

This bespectacled boy also has a microphone attached to his glasses.  He isn't as articulated as the others, only having joints at his neck, shoulders, hips and knees.  His ankles and wrists are not jointed, unlike the others:

Thanks for stopping by, I hope one of you can maybe throw some light on these 'characters', just out of curiosity!

UPDATE!
A friend of mine in the US sent my photos to her son and he remembered seeing something like these characters in a cartoon on the Cartoon Network TV channel back in the 1990s.  I decided to search on that and have now found the show these characters came from!
It was called Code Lyoko and is actually FRENCH!  The final episode ran on the 19th December 2013!  And he was a little out on timing, they apparently first aired in 2003.  And I found lots of information on Wikipedia, here

A lot of the information I read says that there are a group of 5 students but in the photo below there are six and yet in others there are only 4.  I wonder if there is another little fellow out there waiting to be brought home to join the rest of his friends? :)

So mystery solved!  I'm glad that finally I know who these little dolls represent!

Thanks again for stopping by :)
